Discovered my 04 Yamaha F225 with 1200 hours Lower unit leaking oil at the perfect time as Fishing season is now starting to kick off. Went to my local shop to pick up some more fluid and they are booked till Oct! Is my season over or can I just keep filling the LU fluid and run till mechanic can fix. Shop said its not good cause the pressure built will just push the fluid out and it is unkown when it will let go. Sorry I am not familiar with outboards but when you get leaky tranny in a car its not the end of the world just stay on top of fluid loss. Hoping this is the same and you experienced guys chime in. Im ready for the snide comments coming. Will Look into how to vids to do all the seals myself cause I'd be crushed if my season is over. Same time I dont want to grenade anything.

    Yamaha USA will have to increase service centers and certified mechanics in So. Cal if they want to sell any more outboards. It’s just ridiculous anyone has to wait four or more months to get service and or parts!

    Good luck !

    Certainly room for some service centers. I think they should push outboards on some of their larger motor cycle dealerships.

    If you know how to turn wrenches, there are several You tube videos on how to change out the seals on Yamaha lower units as you mentioned in your post

    Make sure it is gear case oil and not crankcase oil

    If oil is leaking out, then it's likely water is getting in. If water contaminates the oil and gets to the bearings, you will have an expensive problem on your hands. Try to isolate which seal is leaking, and if you think you can handle it, change the seal.

    Boats.net or Simm should have the parts to you quickly. Do not be tempted to run it because it is a slow leak. Water can get in and grenade your lower unit, then you are screwed.

    Just be careful not to scratch the prop shaft when removing the seals as any scratches can ruin the new seal very quickly They generally pop pretty easy.

    Good luck

    Parts are already on its way from Boats.net. Tried Sims but they are busy and returned my call too late. I watched several vids and lucky for me I can handle many repairs myself. I didnt go fishing afterall as conditions sucked anyways and will have it fixed by 4th of July. 4

    Hey Joey;

    While you are there, better check the exhaust if you haven't already. Let me know if yo built a lower unit stand.

    good luck
